This update of Microsoft Azure Backup includes improvements to provide more detailed information about the stage of backup and more actionable error messages. A few examples of this include reporting errors about incorrectly-specified cache-folder location and providing write-permissions to the recovery target location. Additionally, Azure Backup can now detect and apprise users of any unsupported configurations, thereby preventing associated backup errors.
